Tostop creeping oi' the oil alongthe shaft :22 within the chamber Q3, said shaft is formed with a circumferential groove 26, the inner wall of which inclines toward the inner end ot' the bushing hearing portion 20 and the outer Wall oi' which forms a sharp or abrupt shoulder, `whereby movement of theoil along the shaft is stopped and the oil is thrown or caused to drop into the chamber E23, from which it is returned to the pump, as above described.

The end lll contains an inlet passage .27 opening into the lubricant chamber lti and is provided with a familiar closure device 28 (Fig. l) v From the foregoing it Will be seen `that my present invention overcomes an existing objection and difiiculty, arising out oit the iiact that it desirable to prevent leakage and loss of oil from machines of this cliaracter. The present device comprises efficient means "for trapping and returning the oil `to the machine, and preventing its escape therefrom.

The invention is capable of useful en'ibodiment in machines for various purposes, and the specific structure and relationship ot parts may be modiiied `as needed Without departure from the nature and scope oi the invention I. do not restrict myseli2 in any unessential particulars, but What I claim and desire to secure by Letters Patent is :M

l. Thecombination with a support, spaced walls forming a chamber in said support, and a rotary shaft extending through said Walls and said chamber and provided with a cir 'cumferentiall groove in said chamber, of a unitary hearing bushing element in Which said shaft is'journaled, said bushing element extending across said chamber and being mounted in both of said Walls and having a chamber of larger diameter than the shaft and enclosing said groove and having a. discharge outlet from said bushing chamber to said first chamber.

2. The combination with a support, spaced walls forming a chamber in said support, and a rotary shaft extending through said support and said chamber and provided with said shaft is journaled, said bushing element extending across said chamber and being mounted in both oitl said Walls and having a chamber ot larger diameter than the shaft and enclosing said groove and having a discharge outlet troni said bushing chamber to said lirst chamber, a u'all in connection with Ysaid support 'forming a lubricant containing chamber around said shaift, and an extension ot said bushing across said lubricant containing chamber and having its end mounted in said lastanuned wall.

3. The combination with a support having Walls Llkirming a chamber therein7 oit a shalft extending through said Walls and said cham ber and having a circumferential groove in said chamber bounded on one side by an inclined wall and on the opposite side by an abrupt wall 'toi-ming an approximately radial shoulder, and a unitary beariilg bushing elcnient extending across said chamber and mounted in and forming impervious joints u'ith said Walls and having a chamber therein around an d ci larger diameter than said shaft and enclosing said groove, said bushing element having an opening from said chamber therein to said chamber in said support.

4t. ln a machine of the cha actor described, a cylinder having a liquid inlet passage and an air inlet passage opening into said liquid inlet passage, a shatwextending into said cylinder and provided with a circumferential shoulder outside ot said cylinder, a bearing bushing through which said shaft extends having a chamber enclosing said shoulder and having an outlet from said chamber, and means for conducting liquid discharged from said bearing bushing to said liquid inlet opening.

bushing through which said shaft extends J OSEPH J. JANCA.
